Processing details
■Operation processing
• These functions convert the DINT type data input to (s) to WORD type data and output from (d).
• The information stored in high-order 16 bits of an input value is discarded. (Refer to (1) in the figure below.)

(1)
• A value input to (s) is the DINT type data value.
■Operation result
1.
Function without EN/ENO
The operation processing is executed. The operation output value is output from (d).
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
Execution condition
EN
TRUE (Executes operation)
FALSE (Stops operation)
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
When DINT_TO_WORD(_E) is executed, the information stored in high-order 16 bits of the DINT type data
value input from (s) is discarded.
